CHARLES JOHN GLASEL, OF NE YORK, N. Y.

AUTOMATIC TANNING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 782,193, dated February 7, 1905.

Application filed October 3, 1903. Serial N 175,694 '4' Be it known that I, CHARLES J OHN GLAs an, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Automatic Tanning-hiachines; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to automatic tanningmachines, and has for its object the novel construction and arrangement of its parts, whereby the hides or skins may be quickly secured to removable frames, which are adapted to be placed in the cylinder and rotated therein with the hides while the latter are subjected to the spray of certain liquids used in depilatory tanning and coloring leather. These and other objects of this invention are described -in detail in the following specification and more clearly pointed out in the appended claims.

In the drawings forming a part of this specification, and in which like reference characters refer to the same parts in the various ligures, Figure 1 is a side elevation of my improved automatic tanning-machine. Fig. 2 is a longitudinal vertical section of the same automatic tanning-machine. Fig. 3 is a side elevation withpart of the casing broken away to show the interior arrangement of the parts when the frames carrying the hides are being removed from or returned to the cylinder. Fig. sf is a transverse section on the line t e of Fig. 2. Fig. :3 is a transverse section on the line 5 5 of Fig. 2. Fig. 6 is a detail view of one of the hooks which secure the hides to the frames.

My improvements are embraced in a cylinder l, preferably made of some non-ferruginous material and having heads 2 and 3, the head 2 having an opening which contains a sleeve &, while the head 3 is solid. The cylinder near each end is provided with annular rails 5, which travel in grooved rollers 6, suitably earried in bearings T and supporting the cylinder and permitting its rotation in either As shown in Fig. &, these bear direction.

ings may at one end of the cylinder be adjusted longitudinally with relation thereto in order to secure the perfect movement of the rail in the rollers.

\Vithin the cylinder and adjacent to the head 2 is a partition 8, secured to the cylinder and having an opening for the reception of the sleeve i. In the space formed by the partition and the head is carried the liquid for treating the hides, and it is admitted through an opening closed by the plug 9 and into a centrally-dis 'iosed tank 10 through the valve 11 and out of the tank 10 through a valve 12 into a space 13, which communicates with a pump lei, whose suction-rod 15 is actuated by the eccentric groove US of the disk 17.

The outer end of the sleeve i carries a pulley 18, which is driven by the pulley 19 on the driving-shaft 20 through the medium of the belt 21. The shaft 20 carries two of the rollers 6 at one side of the apparatus and is also provided with a pulley 22, through which it receives its motion. To the inner end of the sleeve st is secured a second hollow shaft 23, carrying a series of circular perforated frames 24 and 25, the latter being secured to the shaft, while the former are loosely disposed thcreon and adapted to move in directions as shown. The movement of the frames 24 is effected by means of the cam-groove 26 in the outer surface of the sleeve 27, secured between the shoulder 28 of the shaft 23 and the disk 17 and rigidly connected with the cylinder by means of radial rods 29, which are adjustable in the bearings 30, carried by the cylinder, and enter perforations 31 in the sleeve 27. The shaft 23 has longitudinal grooves 32, in which play rods 33, carrying at one end lugs or rollers 3a, which play in the groove 26, and have at the other end lugs 35, by which the rods are locked to the sliding frames by means of tangential keys 36, as shown in Figs. 2 and Near the outer edge of the frames 2% and and on the faces which cooperate are arranged hooks 37, (shown more clearly in Fig. 6,) each hook having a perforated spring-lock or snap which is adapted to close down upon it after the hide has been attached. These snaps on each frame are all simultaneously disengaged from their respective hooks by a hoop or ring 39, which when forced back toward the frame causes an upward and backward movement of the spring away from the i these pipes are shown, it is obvious thatI may employ a greater number of them. Likewise I may vary the size and number of perforations as the occasion may demand.

Within the shaft 23 is carried a second hollow shaft 41, whose outer reduced end 42 is supported in bearings in a partition 43 within the end of the cylinder closed by the head 3, and the apparatus is strengthened by the bolts 44, which pass through the head and into the bearing. At one point of the edge of this partition is an opening having a door 45 for the removal of sediment, &c. Near the outer end of the shaft 41 is a circumferential groove 46, in which play the ends of adjustable pins 47, carried by the shaft 23, and while permitting the two shafts to rotate independently cause the shaft 23 to move longitudinally with the shaft 41 at certain times. The inner end of the opening in the shaft 41 carries a nut 48, secured to it by means of screws or pins 49, and through this nut plays a screw 50, one end being journaled in the shaft 41, While the other end is carried by the shaft 4 and on the outside thereof provided with a pulley 51.

The cylinder may be provided with interior bracing-rings 52 and at certain points with receptacles 53 for certain ingredients which may be useful in the tanning or coloring of the hides. Outlets 54 and 55 are also provided to drain the cylinder and the space formed by the head 2 when it is so desired, and the frames 25 are provided with rollers 56, the object of which will be explained later.

The operation of the machine is as follows: The hides to be treated are stretched on the hooks 37 and 37 a between a stationary and a moving frame or on lines radiating from the center of the cylinder, and when the power is applied to the rollers which drive the cylinder and rotate same the pulley 18 is rotated in the'opposite direction, carrying with it the shafts 4 and 23 and the hide-carrying frames 24 and 25. As the hides pass the perforated pipes they are subjected to a forced spray from the liquid in the space 13, and

those remaining in the bottom-of the cylinder by means of the pump 14, which is carried by the cylinder proper, while the operating-disk 17 is rotated by the pulley 18. The sleeve 27 is controlled by the movement of the cylinder, while the shaft 23; carrying the rods 33, travels in a reverse direction, and the groove 26 causes the rods to reciprocate, moving the frames 24 to and fro with relation to the frames 25 and stretching the hides and then allowing the same to contract, thus opening and closing the pores of the skins as the solution is sprayed upon them and causing the hides to absorb the solution and become permeated rapidly and economically. \Vhen this treatment has been concluded and it is desired to remove the treated hides and renew the operation with fresh ones. the head 3 is removed and the partition 43 taken out. This leaves the shafts 23 and 41 unsupported at this end of the apparatus until a track 57, Fig. 3, is put into position beneath the roller 56 of the outer frame 25. the rods 29 are withdrawn from the openings 31, and a belt 58 is then placed on the pulley 51, so as to rotate the screw 50 and cause the nut 48 to work outward along its length, carrying with it the shaft 23 and the frames 24 and 25. WVhen these parts are so propelled to the outside of the cylinder, the treated hides are removed and the frames are replenished .with skins for treatment and carried back into the cylinder and the head 3 secured in its place.

It is evident that the pipes 40 may be used to supply the cylinder with certain gases or fumes, if so desired, and various modified forms of details may be resorted to to accomplish the ends sought. The stationary frames 25 may also slide loosely on the shaft 23 and be provided with actuating-rods, and the lugs connecting these rods with the frames may be adjustable along the length of the rod, so that the frames may be adjusted to any degree of proximity to provide for hides of different kinds and sizes.

IVhen the shafts andframes are removed with the treated hides, a similar set of shafts and frames with hides to be treated may be prepared and put into position and carried into the cylinder by the reverse action of the screw 50 and the new set of hides be put through the abovedescribed treatment while the treated hides which have been removed are being taken from the frames and the latter replenished. The screw and mechanism for expelling the shaft may be reversed and so connected with the shaft that it will be carried by it and work against the cylinder-head when operating.

Instead of a screw it is obvious that I may use any well-known mechanical means to remove and reinsert the shaft with the frames and hides without departing from the broad idea herein described and claimed.
